Enzymes.
They lower the activation energy (amount needed to start a reaction) and increases the reaction rate.
I think that is might be 25%. I hope that helps.
The following statements apply to autotrophs only:
1. Make their own food.
2. Use inorganic materials to produce energy.
3. Producers.
4. Many use photosynthesis to produce organic compounds.
The following statements apply to heterotrophs only:
1. Consumers.
2.Rely on other organisms for energy.
3. Unable to produce organic compounds from inorganic materials.
4. Obtain their food by consuming other organisms.
Generally, autotrophs are plants, which are capable of trapping the energy of the sun to produce their own food. That is why they are called producers. They have the capacity to produce organic compounds using inorganic raw materials. Other living organisms depend on the foods produced by autotrophs. The heterotrophs do not have the capacity to produce their own foods so they depend on the food produce by autotrophs, they also feed on other living organisms. That is why they are called consumers. <span />
